DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention is explained in more details below with reference to figures which show only an embodiment.

The directions mentioned in the invention are based on the directions in FIG. 1.

A manually drivable food cutter shown in FIG. 1-5 includes a cap 1, a base 2, a gear shaft 3, a blade shaft 4 and a vessel 5.

There is an axle journal 10 on the cap 1, and on the base 2 there is a gear part which includes four gears 201,202,203,204. The big gear 201 and the small gear 202 are set in the middle, and the left gear 203 and right gear 204 are set respectively on the left and on the right. And the big gear 201 gears into the upper part of the left and right gear 203,204, while the small gear 202 gears into the lower part of the left and right gear 203,204. In the middle of each of the left and right gear 203,204, there is a slot for the mounting member 230,231 to go through and fix the left and right gears 203,204 on the surface of base 2 respectively; the lower end of the gear shaft 3 is connected to the upper end of the blade shaft 4, and the upper end of the gear shaft 2 goes through the slots in the middle of big gear 201 and small gear 202 sequentially to connect to the axle journal 10 on the cap 1; the upper end of the blade shaft 4 connect to the gear shaft 3 via the orifice 22 on the surface of base 2, and on the blade shaft 4 there is one or more blades 41; the vessel 5 for containing food which is going to be processed is a transparent cup, and can be lid by the base 2. On the inner bottom surface, a axle journal 50 is set approximate axially, the blade shaft 41 is connected to it and can rotate freely.

In the case of suing the apparatus, the vessel 5 should be held in one hand, and the cap 1 should be screwed by the other hand, when the cap 1 turns, the axle journal 10 of cap 1 can transmit the rotation to the big gear 201 in the middle. For example, when the cap 1 is turned clockwise, the big gear 201 in the middle will make the left and right gears 203,204 rotate anticlockwise; at the same time the lower part of the left and right gears 203,204 make the small gear 202 rotate clockwise, so the blade shaft 4 rotates with the gear shaft 3 of the small gear, the blades 41 cut the food in the vessel, and the construction mentioned above can make the rotation of blades 41 more swift and make the operation more laborsaving because of the gears used.

There are one or more wedges 21 on the inner edge of the bottom of the base (see FIG. 3, 4), and there are also one or more corresponding slots 40 on the outer edge of the upper surface of the vessel. When the base 2 covers on the vessel 5, the wedge 21 will be adjusted to the position of the slots 40 and screwed slightly clockwise, the base 2 will be stuck to the slots 40 on the vessel to make sure that the whole structure will not fall apart while being used.
